Answer:
The correct option is c.
Step-by-step explanation:
An experiment in a physics class involves dropping a golf ball and recording the distance in meters it falls for different times in sec.
The given data is
Time Distance
0 0
0.5 1.2
1 4.9
1.5 11.0
2 19.5
2.5 30.5
3 44.0
The equation of linear regression line is defined as
The value of b is 14.657 and the value of a is -6.1143
The equation of linear regression line is
The value of R² is 0.9228.
Therefore option c is correct.

Y - x
M also mean slope if you don’t know
d,
If you change the y-intercept but keep the slope the same, it just moves the line up or down. Since the lines would have the same slope (same rate of change), the two lines would be parallel.
Answer:
Answer is below
Step-by-step explanation:
Multiply both sides by -9
Add 5
Divide both sides by 2
